NOTES:
1. Assumes CLKOUT, CSn, BSn, OE, AS, ADDR[21:0] and DATA[15:0] are configured for full drive strength (via the PIM).

2. The CSn, BSn, OE and AS signals are synchronous to the falling edge of CLKOUT. Therefore, changes on these
signals are triggered by the falling edge of CLKOUT, even though they are specified in relation to the rising edge.
